Error opening xlsx, __init__() got an unexpected keyword argument 'fLocksText'

Strange error on load_workbook(), win 10 x64, python 3.7, openpyxl==2.5.8:

wb = load_workbook(input_file)
  File "D:\Miniconda3\lib\site-packages\openpyxl-2.5.8-py3.7.egg\openpyxl\reader\excel.py", line 276, in load_workbook
    for c in find_charts(archive, rel.target):
  File "D:\Miniconda3\lib\site-packages\openpyxl-2.5.8-py3.7.egg\openpyxl\chart\reader.py", line 50, in find_charts
    drawing = SpreadsheetDrawing.from_tree(tree)
  File "D:\Miniconda3\lib\site-packages\openpyxl-2.5.8-py3.7.egg\openpyxl\descriptors\serialisable.py", line 84, in from_tree
    obj = desc.expected_type.from_tree(el)
  File "D:\Miniconda3\lib\site-packages\openpyxl-2.5.8-py3.7.egg\openpyxl\descriptors\serialisable.py", line 84, in from_tree
    obj = desc.expected_type.from_tree(el)

    return cls(**attrib)
TypeError: __init__() got an unexpected keyword argument 'fLocksText'

Also tried with openpyxl==2.6.0.dev0 branch, same error.

2.5.0 - error

2.4.11 - works, so, for googlers, temp solution for this (if your file don't need 2.5-2.6 functionality):

pip uninstall openpyxl
conda uninstall openpyxl
pip install openpyxl==2.4.11

Thanks for the report and the file. The problem is related to a shape in the worksheet. 2.5 and later try to load images and charts but earlier versions don't which is why you're seeing the behaviour you are.

Add missing attribute definition. Resolves #1106
